We compared the morphology of gully sedimentary fans on Svalbard as possible analogs to gullies on Mars in order to constrain whether fl uvial and/or debris-fl ow processes are predominantly responsible for the formation of Martian gullies. Our analysis is based on high-resolution imagery (High Resolution Stereo Camera [HRSC-AX], ̃20 cm/pixel) acquired through a fl ight campaign in summer 2008 and ground truth during two expeditions in the summers of 2008 and 2009 in Svalbard, compared to high-resolution satellite imagery (High Resolution Imaging Science Experiment [HiRISE], ̃25 cm/pixel) from Mars. On Svalbard, fl uvial and debris-fl ow processes are evident in the formation of gullies, but the morphological characteristics clearly show that the transport and sedimentation of eroded material are predominated by debris fl ows. Most investigated gullies on Mars lack clear evidence for debris-fl ow processes. The Martian gully fan morphology is more consistent with the deposition of small overlapping fans by multiple fl uvial fl ow events. Clear evidence for debris fl ows on Mars was only found in one new location, in addition to a few previously published examples. The occurrence of debrisfl ow processes in the formation of Martian gullies seems to be rare and locally limited. If predominantly fl uvial processes caused the formation of gullies on Mars, then large amounts of water would have been required for their formation because of the relatively low sediment supply in stream and/or hyperconcentrated fl ows. Repeated seasonal or episodic snow deposition and melting during periods of higher obliquity in the recent past on Mars can best explain the formation of the gullies. © 2011 The Geological Society of America.

Disclosed herein are a materials such as a coating, an elastomer, an adhesive, a sealant, a textile finish, a wax, and a filler for such a material, wherein the material includes an proteinaceous molecule such as a peptide and/an enzyme that confer a metal binding, an anti-fouling and/or an antibiotic property to the material. In particular, discosed herein are marine coatings such as a marine paint that comprise an anti-fouling peptide sequence that reversibly binds a metal cation that is toxic to a fouling organism. Also disclosed herein are methods of reducing fouling on a surface by treating the surface with a metal binding peptide.


Disclosed herein are polymeric materials such as a coating, a plastic, a laminate, a composite, an elastomer, an adhesive, or a sealant; a surface treatment such as a textile finish or a wax; a filler for such a polymeric material or a surface treatment that includes an enzyme such as an esterase (e.g., a lipolytic enzyme, a sulfuric ester hydrolase, an organophosphorus compound degradation enzyme), an enzyme (e.g., a lysozyme, a lytic transglycosylase) that degrades a cell wall and/or a cell membrane component, a biocidal or biostatic peotide, and/or a peptidase. Also disclosed herein are methods of altering a materials property such as service life, flexability, or rigidity, by incorporation of an enzyme into a material capable of being chemically crosslinked by the activity of a lipolytic enzyme, a hydrolase, and/or a urease.
